FutureGuide®-BIS-B ITU-T G.657.A2 (Superior Bend Insensitive Fiber + ITU-T G.652.D compliance)

Recent trends in optical fiber networks demand optical fibers having reduced attenuation to help long distance transmission and bend insensitiveness for harsh installation conditions. FutureGuide®-Ace is an enhanced fiber categorized as ITU-T G.652.D from Fujikura. It offers zero(low)-water peak attribute that enables all-band transmission and superior reduced-attenuation characteristics, while converging bend insensitiveness complying with ITU-T G.657.A1. Also the fiber ensures backward compatibility with all existing conventional networks based on G.652 fibers. FutureGuide®-Ace helps cable manufacturers to design cost-effective and aggressive higher fiber-count cable designs that assist telecom operators to plan for higher fiber density installations. Furthermore, reduced attenuation characteristics ensure longer transmission distance with less number of amplifiers and thus contributes to the reduction of total cost. FutureGuide®-Ace is suitable from long-haul to access networks of 40Gbps, 100Gbps and beyond.

In 1976, Fujikura achieved the world's lowest attenuation record, 0.47dB/km. Ever since then Fujikura has always been the industry's leading optical fiber manufacturer. ITU-T G.652.B is the most commonly used optical fiber for long-distance terrestrial application.

Optical fiber networks in urban areas demand more effective utilization of available space by installing high density and more fiber-count cables underground. Especially, such demand is increasing in access network. Employing our innovative fiber coating technology in FutureGuide®-BIS-B, we launch a new ITU-T G.657.A2 fiber with 200μm coating diameter named FutureGuide®-BIS-B-200. The fiber has drastically reduced coating diameter, while keeping microbend characteristics equivalent to conventional fibers. The 200μm coating diameter with tolerable microbend performance allows around 40% reduction of cable cross-section area. In addition, superior macrobending performance helps to install optical cables into narrower spaces with easy handling. This new fiber strongly contributes to not only more effective utilization of available space but also saves costs of manufacture, transportation and installation of cables.

FutureGuide®-SS is designed with small-dispersion slope, optimizing for the use of wider range of wavelength with relatively smaller chromatic dispersion at 1625nm region. FutureGuide®-SS is suitable for DWDM application in C- and L-bands.
